Abstract
Abstract A composition for reducing the loss of liquids by seepage through permeable ground surfaces is shown. The composition desirably comprises an aqueous emulsion of asphalt including a combination of cationic emulsifiers, a nonionic surface active agent and preferably a minor proportion of elastomer solids. The compositions are adapted for spray application on natural and man-made beds of rivers, ponds and other water impoundment and transfer structures. The stability of the emulsion is controlled so that penetration of the soil is achieved and a flexible water impervious mass is obtained.
